The Indoor Multifunction Stadium (IMS) or Indonesia Arena Stadion in the Gelora Bung Karno Stadium complex is the most ambitious stadium project that only requires 20 months of construction until it is ready to become the main venue used to facilitate the 2023 Basketball World Cup last August with Indonesia as the host.

This international standard building has a capacity of approximately 16,000 people and is designed by placing modern concepts, adopting environmentally friendly guides, and prioritizing safety as the most critical aspect in sports facility projects. 

These three aspects are realized with various design approaches and the use of materials to support the basic concept according to basketball stadium regulations by the International Basketball Federation (FIBA). One of them is the application of steel material for Indonesia Arena Stadion roofing systems.

The configuration of the roof system for an international standard sports facility is important because it must pay attention to safety aspects, green building concepts, and environmentally friendly. In its construction, Indonesia Arena Stadion uses Colorbond steel roofs with features to support the realization of green and environmentally friendly buildings. 

Indonesia Arena Stadion roof design adopts the concept of Indonesian craftsmanship with woven patterns as a form of local wisdom. The steel roof is designed as part of the building's skin and has a dual function. Therefore, the efficiency and effectiveness of this building can be optimized for the function of the roof as well as the skin of the building.

Thus, the energy consumed for the Indonesia Arena Stadion air conditioning system will be lower, and natural lighting during the day can be maximized properly. Overall, the Colorbond steel roof design will save energy consumption by 30.74%. In addition, this steel roof has strong weather resistance even when extreme weather happens, as evidenced by weather clinical trials in Australia.

Safety aspects are also considered in this roof design, where one of the features of Colorbond steel roofs is stimulated to be resistant to fire and help the extinguishing process in the event of a fire. This aligns with the technology conceptualized in the Indonesia Arena Stadion building. 

The selection of gull-gray residents on the roof and skin of the Indonesia Arena Stadion building is based on general environmental adjustments in the Gelora Karno complex. In addition, this color is considered neutral and can display an elegant modern aesthetic image for an international standard sports facility. 

With the facilities and fulfilled international standards, this stadium isn't only used for basketball but can function for various other indoor sports activities such as ice hockey and even equestrian. In addition, it also can be used for large-capacity entertainment events like music concerts, exhibitions, and other arts activities.
